Procedure
Using the procedure described in Example 103A, 1-(5-tert-butylisoxazol-3-yl)-3-[3-(7-hydroxy-6-methoxyquinazolin-4-yloxy)phenyl]urea from Example 95B (0.45 g, 1 mmol) was reacted with tert-butyl 4-hydroxypiperidine-1-carboxylate (0.242 g, 1.2 mmol) in the presence of Ph3P (0.393 g, 1.5 mmol), and di t-butyl azodicarboxylate (0.345 g, 1.5 mmol) in THF (10 mL) at room temperature overnight, to afford tert-butyl 4-(4-{3-[3-(5-tert-butylisoxazol-3-yl)ureido]phenoxy}-6-methoxyquinazolin-7-yloxy)piperidine-1-carboxylate as a crude product. LC-MS (ESI) m/z 633 (M+H)+.
